Big Ambitions September 2026 Patch Notes

Twelve days after the 28 August 2026 full release, Hovgaard Games shipped three post-launch fix waves. Build 3672 landed on 1 September 2026, with Build 3674 following as a near-immediate hotfix. Build 3675 arrived on 10 September 2026 as a larger patch addressing AI behavior concerns raised by the community. This page covers what all three builds changed, what players reported in the first two weeks, and what is still being investigated as of mid-September 2026. For launch-day notes, see version 1.0. For the roadmap that follows these fixes, see roadmap.

The community response to launch was large and enthusiastic. Hovgaard reported over 12,000 concurrent players at peak — a studio record. That many people in a new build meant the bug reports were fast and specific. The fixes below reflect that feedback loop.

What Build 3672 fixed (1 September)

Vehicle entry — entering cars and trucks was broken for some players after the 1.0 launch. The prompt appeared but the character did not animate into the seat. Build 3672 patched the vehicle entry state machine. If you still cannot enter a specific vehicle after updating, try restarting the client before filing a report.

Missing Hamptons retail buildings — the small luxury retail strip in The Hamptons had buildings that were absent from the map for players who started new saves after the 1.0 launch. The strip should now populate correctly for fresh saves and existing ones that reload the area. Players who encountered this during the launch weekend can fix it by traveling to The Hamptons and letting the area reload.

Subway destination search — the in-game subway map’s destination search returned no results regardless of what you typed. This broke the fastest commute option for players who rely on public transit instead of driving. Build 3672 rebuilt the search index. Subway routing now works as documented in the controls guide.

Assign Uniforms button — a missing button in the employee management UI made it difficult to bulk-apply clothing presets to staff. The Assign Uniforms control is now present and functional in BizMan and the standalone employee panel.

Bank borrowing clarity — banks now display what you can actually borrow before you commit to a loan. The pre-1.0 behavior of showing only the maximum cap without accounting for income was adjusted. Players should see a more accurate borrowing ceiling in the Santander and other bank interfaces. See banking for the full loan and credit overview.

What Build 3674 patched immediately after

Build 3674 was a rapid follow-up that tightened the same batch rather than adding new fixes. Hovgaard described it as “near-immediate” in the Steam announcement. The main changes:

• Vehicle entry edge case that survived Build 3672 for certain vehicle types.
• Minor stability fixes for large saves that hit a memory ceiling on the first session after launching 1.0.
• Hotfix for the Hamptons strip not appearing for players who installed the game in a non-standard directory path.

If you downloaded 1.0 on 28 or 29 August, you should have received both patches automatically through Steam. Check your build number in the Steam client under Properties — Local Files — Verify Integrity.

What Build 3675 changed (10 September)

Build 3675 was described by Hovgaard as “big patch 2 is finishing up” but released as a hotfix first to address AI concerns. The main changes:

AI behavior fixes — the studio acknowledged community reports about AI-controlled rival businesses making unrealistic decisions, and adjusted the decision-making logic for AI-owned shops. The changes focus on pricing behavior, restocking patterns, and expansion timing. This does not affect your own business AI (employees, logistics managers); it targets rival simulation.

Delivery driver routing — warehouse delivery drivers now follow more reliable routing, especially in Industry City where road layouts caused delivery trucks to miss their destinations.

Subway station naming — several subway stations had display names that did not match their actual transit route. Build 3675 standardized station names across the UI and the in-game transit map.

Hamptons garage access — players who purchased Hamptons properties with garage spaces now correctly see their registered vehicles in the garage menu. This was a reported issue for players who transferred saves from Early Access.

Performance improvements for large saves — builds 3672 and 3674 addressed immediate stability, while Build 3675 includes deeper optimization for cities with 10+ businesses and active logistics networks.

What is still being investigated

Hovgaard acknowledged in the Build 3672 announcement that they are actively looking into two issues that had not been resolved at the time of shipping:

FPS drops and stuttering — a significant number of players reported frame-rate drops in busy areas, particularly in Industry City and during events with high customer density. The studio has not identified a root cause yet. As of mid-September 2026, no fix has shipped. Workarounds recommended by the community: turn shadows off in graphics settings, cap the game at 60fps via driver software, and avoid running the game in fullscreen on multi-monitor setups. If your city stutters, try those before submitting a bug report.

Steam Cloud save conflicts — some players with large saves reported cloud sync conflicts after installing 1.0 over an Early Access cloud save. Hovgaard is investigating. If you are on an old EA save and experience issues after the 1.0 update, Hovgaard asked players to submit saves through their official support channels.

Neither issue had a fix as of September 2026. The system requirements page has the current hardware recommendations; the getting started guide has troubleshooting steps for first-session crashes.

How to follow future patches

Hovgaard posts patch notes on Steam news for app 1331550, on the official Discord server, and on the in-game news ticker. The links page has those URLs. Build numbers are the only reliable identifier — “the latest patch” is ambiguous when two builds ship four hours apart.

The updates hub tracks these notes and the version history. This page will be updated if Build 3676 or a later September patch ships material fixes. The roadmap for what comes after the fix wave is on roadmap.
